Newspaper feature on screen is hit in a big way (8)

Ross

I believe the answer is:

walloped

I'm a little stuck... Click here to teach me more about this clue!

'is hit in a big way' is the definition.
I can't judge whether this definition defines the answer.

'newspaper feature on screen' is the wordplay.
'newspaper feature' becomes 'op-ed' (I've seen this in another clue).
'on' means one lot of letters go next to another.
'screen' becomes 'wall' (I can't explain this - if you can you should believe this answer much more).
'oped' after 'wall' is 'WALLOPED'.

Can you help me to learn more?

(Other definitions for walloped that I've seen before include "Hit hard" , "affected by strikes?" .)
